At the peak of Looney Tunes: Back in Action, Bugs Bunny and Daffy Duck lead Elmer Fudd on a wild pursuit through famous paintings hanging in the Louvre, their animated selves absorbing the painting styles of Salvador Dali, Georges Seurat, Toulouse Lautrec, and others. That sequence manages to recapture the anarchic spirit of Warner Bros.' classic cartoons; unfortunately, not much else in this labored movie does. Technically, the merging of live actors and cartoon characters is impressive, as Brendan Fraser and Jenna Elfman team up with Bugs and Daffy to save the world by keeping a magical diamond out of the hands of the evil Acme Corporation, headed by a nerdy, prancing Steve Martin. Just about every Warner Bros. character makes an appearance, as do Timothy Dalton, Heather Locklear, and the ever-dependable comic delight of Joan Cusack (In and Out, School of Rock). --Bret Fetzer
